Reviewed by Brent Fulgham.
Source/WebCore:
CCECCryptorGetKeyComponents returns components in unpadded formats. In some minor cases, the ECC components
do need padding. Therefore, we occasionally see some corrupted outputs in JWKs. To overcome that, this patch
replaces CCECCryptorGetKeyComponents with CCECCryptorExportKey which does padding all the time.
In the meantime, this patch also makes export* methods return OperationError if any error occur in the
underlying operations though very unlikely.
